Yes, the adj trigger and speed hammer. You want this! Easy to install and adjust. Great trigger.

I got one in my M4gery, the complete JP package with speed hammer. I bought it used in excellent condition from the Equipment Exchange, and I LOVE it! You can get it cheaper from Brownells with a trader discount.

Yes
Yes
NO!
I have purchsed the complete package. It was not easy to install as the anti-walk pins were too big in my BM receiver. My gunsmith installed it, and lightly polished the sear surfaces. 400% improvement. Having said that I would go with the highly regarded Jewell triggers system, my gunsmith told that were truly drop in and that trigger adjustment takes seconds.

The Jewell is a top-notch trigger but it's not a single stage. I think the first thing anyone thinking about getting a new trigger should decide is if they want a single-stage or a two-stage, and go from there. IMHO, the JP and the Jewell are both good triggers, but they're two different animals.

Good point. I wanted the single stage trigger system, so I went with JP.

More to say on the JP:
For a rifle such as the Oly Ultramatch, or other target rifle with its flat top, bull bbl, free floated bbl, etc, this is a great trigger.
I would NOT install it in a SHTF rifle, a LEO entry rifle, or my aound-the-house varmint rifle. The stock parts are a much better choice there.
I found installation no more difficult than installing regular AR-15 parts.

i have the jp and it is excellent. a bud of mine installed a rock river two stage in his oly, and i was very impressed with the ease of assembly and pull. if you like a two stage, this is a cheaper alternative.

And which trigger do you prefer on AR-15's ??
A different/same trigger on say a .308 sniper bolt gun ??

Depends on its intended use. For a tactical/action rifle/SHTF gun I like a single-stage. For highpower/varmint/target gun I like a two-stage. I have a JP single stage for the former and a RRA two-stage for the latter. The Jewell is a sweet trigger and I'd like to have one but the RRA was roughly half the price and it's a nice trigger too, though not adjustable.
Point taken on the suitability of a JP trigger for SHTF or LE use. Besides the possibility of the adjustment screws coming loose at the worst possible time, the trigger pull is pretty light at about 2-3 lbs. Could be a liability issue for a LEO but I'm not a LEO and I train to keep my thumb busy working the safety with my trigger finger just outside the trigger guard.
Edited to add I used blue loc-tite on the set screws and they haven't come loose yet. [:)]

Hey Willy you know thats why I bought another Rock River 2-stage.$120 at the Big Reno Show .it was a easy drop in system an yes what a big difference over the mil-spec trigger an save a little coin for a beggar like me.....

tc6969, you need the JP-RRA-ACCURACYSPEAKS-JEWELL super-duper adjustable non-adjustable single-stage two-stage do-all trigger. [;D]
hehehe... seriously, IMHO I think you should try several triggers out to see what you like. I will say this though. I wouldn't put a two-stage trigger in a SHTF rifle but I wouldn't have a problem with either a single-stage or a two-stage in a benchrest/highpower competition rifle.
You could always slick up your factory trigger by taking out the hammer and trigger pins and polishing them with 0000 steel wool. HTH
